(54) Motor and rotor thereof


(57) A rotor having an improved structure capable of achieving an enhancement in durability and a motor having the rotor are disclosed. The rotor is configured to co-operate with a stator in an electromagnetic manner such that the rotor rotates. The rotor includes a sleeve having a shaft hole, through which the motor shaft extends, rotor cores spaced apart from one another in a circumferential direction of the rotor, and at least one of permanent magnets disposed between adjacent ones of the rotor cores such that the permanent magnets are arranged in a radial manner about the sleeve. First and second cover plates are disposed at opposite sides of the permanent magnets in an axial direction. The first and second cover plates have plate holes respectively corresponding to the through holes of the rotor cores. The rotor cores and the first and second cover plates are coupled by fastening members.
